Why is soap ineffective in hard water?
Wow!! What a beautiful painting!!
But look at your clothes. They have become so dirty.
Why don't you wash them??
No no!! Don't use that water along with soap!!
Please listen!! Fine, then bear the consequences!!
See, you are not able to clean them!!
Do you know why??
This is because you used hard water to clean your clothes.
Do you know what hard water is?
Hard water is the water which contains high amounts of minerals, such as calcium and magnesium, in the form of ions.
So, are these ions of the hard water responsible for soap to be ineffective??
Bingo!! You are right!!
Now, to understand what actually happened, let us recall the activity.
Initially, you drenched your clothes in hard water and then you applied some soap.
When we apply soap, it reacts with the calcium and magnesium ions of hard water to form insoluble precipitate called scum. Scum sticks to the clothes, restricting the cleansing ability of the soap.
